Nectar Premier Copper
8.0/10
- Copper-infused gel foam and phase-change material reduce surface temperature vs standard memory foam
- 14-inch profile with ~3.9 inches of comfort foam delivers deep pressure relief for side sleepers
- 365-night trial window and a Forever warranty cover the full life of the mattress
- Outstanding motion isolation, the all-foam build absorbs movement across zones
- All-foam construction runs warmer than hybrid alternatives even with copper infusion
- Weak edge support, not ideal for sleepers who use the perimeter of the bed
- Slow response feel is a poor match for combination sleepers who move frequently
- Discontinued by Nectar; availability is narrowing to third-party retailers
The Premier Copper is the best memory foam option in Nectar's lineup for hot sleepers. The copper and gel infusion provide a measurable, if modest, temperature reduction, and the thick comfort layer cradles side and back sleepers well. Edge support and responsiveness are the weak points.
What is the Nectar Premier Copper mattress?
The Nectar Premier Copper is an all-foam, bed-in-a-box mattress built around copper-infused gel memory foam. Copper has higher thermal conductivity than standard foam, so it draws heat away from the sleep surface more efficiently, although the improvement is incremental rather than dramatic. Combine that with a phase-change material (ActiveCool HD) in the comfort layer and a cool-to-the-touch copper-fiber cover, and the mattress genuinely sleeps cooler than the original Nectar.
At 14 inches tall, it is thicker than most bed-in-a-box competitors. The construction runs top to bottom: copper-infused cover, ~3.9 inches of gel memory foam with phase-change material, a polyfoam transition layer, and a 6.9-inch high-density support core. The result is a plush-medium feel with a firmness of around 5.5 to 6 out of 10 in independent testing.
Who the Nectar Premier Copper is right for
- Side sleepers under 230 lb: the thick comfort layer distributes hip and shoulder pressure without bottoming out.
- Back sleepers under 230 lb: the medium feel keeps the lumbar supported without forcing the spine into hyperextension.
- Hot sleepers who prefer foam: if you want the classic memory-foam contouring feel but run warm, the copper and gel infusion provide a meaningful, if modest, cooling benefit over standard foam.
- Couples sensitive to motion: all-foam construction produces some of the best motion isolation available in a boxed mattress.
Who should avoid the Nectar Premier Copper
- Stomach sleepers over 130 lb: the medium-soft feel allows the hips to sink too deeply, creating lumbar hyperextension over time.
- Combination sleepers: the slow-response memory foam resists quick position changes and creates a "stuck" sensation for active movers.
- Hot sleepers wanting hybrid cooling: copper foam reduces heat retention compared to standard foam, but it does not match the airflow of a pocketed-coil hybrid.
- Edge users: minimal perimeter support makes it harder to sit on the edge or use the full mattress surface, a common limitation of all-foam beds.
Comfort and firmness
The Premier Copper lands at roughly 5.5 out of 10 on firmness, a medium feel. NapLab's pressure testing puts it closer to a 5 (softer than Nectar's own published 6.5 rating), while RTINGS scores it at 6.5 on their stiffness scale. In practice, most sleepers feel a gentle cradle rather than a firm push-back.
This is a medium-firm mattress zone that works well for pressure buildup patients and couples with different sleeping preferences, because neither partner ends up on a surface that is firmly fixed for one position only.
Performance
Cooling
Copper has higher thermal conductivity than polyurethane foam, and the gel infusion adds a phase-change layer that absorbs heat before it builds. In our testing the surface temperature is measurably lower than the original Nectar, by roughly 1 to 2 degrees Fahrenheit. That is real but modest. For hot sleepers who also need contouring, this represents a useful compromise. If temperature regulation is the primary concern, a coil-hybrid will outperform any all-foam mattress regardless of infusion.
Motion isolation
All-foam mattresses consistently lead on motion isolation, and the Premier Copper is no exception. The thick comfort layer absorbs movement before it crosses the mattress surface. This makes it a strong pick as a mattress for couples where one partner wakes easily.
Edge support
Edge support is the weakest point of this mattress. Without reinforced perimeter coils, the foam compresses noticeably when sitting or lying near the edge. The usable sleep surface is effectively smaller than the mattress dimensions suggest. If you tend to sleep near the edge or share the bed with a partner, this is worth factoring into your decision.
Sagging and durability
The Premier Copper uses a high-density polyfoam support core that is thicker than most all-foam competitors, which helps resist early sagging. Rotate it 180 degrees (head to foot) every three to six months and use a mattress protector to maximize longevity. Nectar's Forever warranty covers manufacturing defects and visible indentations over 1.5 inches for the life of the mattress.
Back pain
The medium feel and body-contouring foam distribute pressure evenly, which helps reduce the localized load that causes back pain in some sleepers. Back sleepers under 230 lb get sufficient lumbar support. For stomach sleepers or heavier back sleepers who need firmer, zoned support, a mattress with active lumbar reinforcement is a better choice.
Construction
- Cover: Copper-infused polyester and nylon blend, cool-to-the-touch. Do not remove or machine wash.
- Comfort layer (approx. 3.9 in): Gel memory foam with ActiveCool HD phase-change material for contouring and heat absorption.
- Transition layer (approx. 2.8 in): Polyfoam that softens the transition between the comfort layer and firm base.
- Support core (approx. 6.9 in): High-density polyfoam base, thicker than average for improved durability and reduced bottoming out.
- Total height: ~14 inches (measured closer to 13.5 inches in independent lab testing).
Trial, shipping, and warranty
- Trial: 365 nights, the longest standard trial in the mattress category.
- Warranty: Forever (Lifetime) warranty covering defects and impressions over 1.5 inches.
- Shipping: Free to the contiguous 48 states. Hawaii and Alaska incur additional delivery costs.
- Setup: Ships compressed in a box; allow 24 to 48 hours for full expansion and off-gassing before sleeping on it.
- Adjustable base: Compatible with adjustable bed frames.
- Flippable: No. The mattress is top-to-bottom directional. You can rotate it 180 degrees for even wear, but not flip it.
- Made in: China.

The Nectar Premier Copper is a competent all-foam option for side and back sleepers who run warm and want excellent motion isolation. Its 365-night trial and Forever warranty are standout policies. The primary drawbacks are weak edge support, slow response for combination sleepers, and narrowing stock availability since Nectar discontinued the model. manufacturing.
Frequently asked questions
Is the Nectar Premier Copper still available?
Nectar has discontinued the Premier Copper and replaced it with the Nectar Luxe Memory Foam. Units are still sold through third-party retailers like Amazon, but stock is limited. If you find it, pricing tends to be lower than the original MSRP.
Does copper in a mattress actually help with cooling?
Yes, copper has higher thermal conductivity than polyurethane foam, which allows it to draw heat away from the sleep surface more efficiently. Independent lab tests show a surface temperature reduction of roughly 1 to 2 degrees Fahrenheit versus standard memory foam. It is a real benefit, but a modest one. A coil-hybrid mattress provides far more airflow through the coil layer than any infusion technique can achieve in all-foam construction.
Is the Nectar Premier Copper good for back pain?
For side and back sleepers under 230 lb, yes. The medium firmness and contouring foam distribute pressure evenly and keep the lumbar from dropping into hyperextension. Stomach sleepers and heavier sleepers typically need firmer support or a zoned construction to keep the hips from sinking too far. See our guide on the best mattresses for back pain for a fuller comparison.
Can you use the Nectar Premier Copper on an adjustable base?
Yes. The all-foam construction is flexible enough to work with most adjustable bed frames. Nectar does not void the warranty for using one, provided the frame provides solid, even support without large gaps.
